     in this study plasma nitriding is applied on nickel–aluminum composite coating, deposited on steel substrate. ni–al composite layers were fabricated by electro-deposition process in watt’s bath containing al particles. electrodeposited specimens were subjected to plasma atmosphere comprising of n2–20% h2, at 500 °c, for 5 h. the surface morphology investigated, using a scanning electron microscope (sem) and the surface roughness was measured by use of contact method. chemical composition was analyzed by x-ray fluorescence spectroscopy and formation of aln phase was confirmed by x-ray diffraction. the corrosion resistance of composite coatings was measured by potentiodynamic polarization in 3.5% nacl solution. the obtained results show that plasma nitriding process leads to an increase in microhardness and corrosion resistance, simultaneously.
